Glycolysis is the initial phase in cellular respiration, and it happens to glucose. Glycolysis is an anaerobic (oxygen-free) process. It occurs within the cytoplasm. Pyruvate is the ultimate result of glycolysis, and its destiny is determined by the availability of oxygen.

It's a cytoplasmic protein.

Is the partial oxidation of glucose (6 carbons) into 2 carbons of pyruvate (pyruvic acid).

Two hydrogen carriers (2 x NADH鈦篐鈦�) were reduced in the process of oxidation.

A total of two ATP molecules were synthesised (four molecules were made, but only two were utilised).

Pyruvate is delivered to the mitochondria for full oxidation (further breakdown).

Large amounts of reduced hydrogen carriers (NADH鈦篐鈦篴nd FADH鈧�) result from this extra oxidation.

In the presence of oxygen, the decreased hydrogen carriers will release their stored energy to make additional ATP. So, compared to pyruvate, glycolysis has a lower oxidation state

NADH is created from NAD鈦篸uring glycolysis. The cell's redox balance must be maintained in order for further glycolysis activities to occur. In the presence of oxygen, ETC generates NAD鈦�. Pyruvate is transformed to acetyl CoA, which enters the TCA cycle and is oxidised to CO鈧�.
